New From Primary Arms: Advanced Micro Dot With 50k Hours Battery Life and Lifetime Warranty


Primary Arms continues to build upon its reputation for making solid red dots at an affordable price. In a recent e-mail blast, they’ve announced the new MD-RB-AD (microdot, removable base, advanced). It’s a compact optic with a 2 MOA dot, removable T1/H1-compatible base, rotary brightness adjustment knob, 50,000 hours battery life, IP57 waterproof rating, and a lifetime warranty. All for $149.99, which ain’t so bad at all. More photos follow, and details are available on the MD-RB-AD product page here.

TTAG has a full review of this little guy in the works now, so stay tuned.

    Is this for a pistol or a rifle?

    1. avatar Jeremy S. says:

      Yes. (But mostly rifle. It’s a bit big and heavy to go on a slide that reciprocates, but would be great on a pistol with a fixed top rail like a Mk IV or whatever)

  2. avatar Yes says:

    Rifle sized micro red dot “scope”. Think aimpoint micro.

  3. avatar strych9 says:

    IPX rating is 5 or is it 7?

    1. avatar pwrserge says:

      5 is the dust rating 7 is the water rating. 57 is unusual, but not unheard of.

      1. avatar strych9 says:

        Ah, it’s a different rating system. I though they were trying to say it was an IPX water rating and had a typo.

    2. avatar Anonymous says:

      Doesn’t matter. In about two years their o-rings disintegrate.

    Awwweeee… thats so adorable!… the chinese figured out how to rip off the Sweedes.

    1. avatar Shotgun Sam says:

      The Chinese are not knocking off the sweeds and Americans, it’s the buyers of that cheap stolen intellectual property that does the damage.

      So why are gun shows simultaneously packed with chest-pounding self-declared patriots but also endless tables of knock-off Chinese crap? And all the fake logos of Magpul trijicin Leupold browning aimpoint eotech benchmade surefire Gerber leatherman and the list goes on and on.

      1. avatar Texian says:

        If someone makes a good red dot for a reasonable price for the rest of us who do not wish to spend more on a micro dot than we did building our rifle what’s the problem. The big brands c after to the Gucci crowd, their products shouldn’t cost what they do, but they will always be that price as long as fools are willing to part with their money. Same reason vehicles now cost cost as much as a house.

        1. avatar No one of consequence says:

          “their products shouldn’t cost what they do,”

          Because nobody should get compensated for doing research, development, and figuring out how to do new things before anyone else could, right?

          Also known as socialism.

        2. avatar neiowa says:

          Keep on supporting the “R&D” and production capacity of the PLA. Will work out well or our young men.

          Vehicles are expensive because of Fed gov’t mandated crap and useless BS accessories you purchase. Accessories that have add an incremental cost of $1 to that pickup and increase the price by $5 to buy and an additional $10 over the vehicle life to maintain.

        3. avatar Texian says:

          To both of you who replied.
          I understand r&d cost money. But this is a red dot, not a rocket. They also have military contracts that more than covered all of the r&d. No socialism involved, just free market economy. If it was a rip off, aimpoint would sue. If you wish to spend 3 or 4 times the mmooney to get a similar product go ahead.

          Federal mandates don’t account for the huge increase in price. Remember back when fuel was 5 dollars a gallon? Trucks that usually go for 60 to 70 thousand then were going for 25 to 35 thousand. I guarantee you the stealerships and parent companies were not taking a loss. You are getting screwed, and they have convinced you that you like it.

        “The Chinese are not knocking off the sweeds and Americans, it’s the buyers of that cheap stolen intellectual property that does the damage.”

        That’s a legitimate bitch about the Chi-Coms and their blatant theft of IP.

        Got a *workable* solution for it?

        We can ban Aimpoint imports, and create a whole new market with smuggled goods. Because that works so well with *drugs*.

        Because when comes to buyers with limited cash saving money, shame just isn’t gonna cut it, Sam…

        1. avatar Shotgun Sam says:

          How about this…Have gun shows actually enforce their rules about selling knockoffs. Oh wait, that might cut into their bottom line and cause a rabid 2A backlash from those entitled cheapskates who couldn’t care less about America when it comes to their own wallet. Keeping America safe and economically secure is someone else’s problem. Leaching is a way of life, not a country.

        2. avatar Fred says:

          If this is IP Theft, then get a court order.

          It’s not IP theft. Hence no court order.

        3. avatar Shotgun Sam says:

          You’ve got to be kidding. Even Microsoft can’t stop the chicoms from stealing IP. As is obvious here the gun community is split on whether or not IP theft and patent infringement are fine especially when it supports China and the buyer can pretend they’re one of the cool kids.

          When I see a Primary Arms or other knockoff kit I get the hell away figuring the shooter’s intellect and skill matches their gear.

          Call me a snob but if you think price is the only difference between the real stuff and the lookalikes, well then I rest my case.

        4. avatar Fred says:

          Read the patent laws, and case law surrounding it.

          Patents don’t last forever. Many things the laymen believes would be patentable would not be. Many patents are erroniously issued, and are not enforceable.

          Is China ripping off IP by making forks? Are you paying the Chinese for using gunpowder?

          I support IP laws and enforcement of the same. But, the details do matter. So, No. I am not kidding.

          “Lookalike” is not a legal term and you can’t enforce that. Just as ‘Finders Keepers, Losers Weepers’ falls just as flat, as you may be shocked to find out.

        5. avatar Shotgun Sam says:

          Obviously you are a Chinese plant. No point in presenting facts as those will just be counterfeited as well. Must be calming not to have a soul. But lonely I bet.

  5. avatar Rusty Chains says:

    I have one of their red dots on an AR pistol. Might be time to retire it to the Sub-2000 and pick up one of these for the AR.

  6. avatar Cpt. Obvious says:

    I like the texture choice on the caps. The lifetime warranty is perhaps a sales gimmick, of a sort. When the first version of these came out a few years ago (with buttons rather than a power wheel), all of youtube was testing its’ “Aimpointness” by dunking it underwater, boiling it, freezing it, smashing the ice off of it, dropping it out of buildings, one channel even mounted it to an AK, bashed it into trees etc, and dragged it down a gravel road behind a pickup truck. They managed, finally, to slightly crack a lens, but not only did it still function… it was still Zeroed In. They’re crazy-tough.

    So .. like the Aimpoints they copy, .. since they essentially cannot be destroyed, a lifetime warranty would be on the “up & up”, but no real difference in quality from their previous offering, it was already top drawer.

    1. avatar Nigel the Expat says:

      I might have been one of those people…heh.

      I keep the completely torn up MD-06L and take it to range days now and then for people to play with. Still runs, still holds zero, looks like a trash compactor ate it.

  7. avatar Geoff PR says:

    “TTAG has a full review of this little guy in the works now, so stay tuned.”

    So, we can expect to see that review in *5* years, since I would hope a “full review” would test that claim of a “50,000 hour battery life”…? 😉

  8. avatar Nanashi says:

    Nice. I’ve seen SPARC II/AR go for as low as ~120, but this seems like the standard price. 6.5+ year battery life is nice too. Maybe I should commit blasphemy and pair with this a Midwest Industries AK mount?

  9. avatar Jon in CO says:

    I really like the vortex Sparc series Dots. I love Aimpoint, but $750+ for a red dot is mighty steep for my layaway-type budgets. Same thing for Acogs and the like. I’ve never purchased or used any other brands, so I’m curious to perhaps try this one. I’ll wait for their Black Friday specials and see if it comes down in price further.

    If the Aimpoint T1/H1/T2 series we’re perhaps sub $450, I’d be much more prone to buying one.

    Sweden is much more ‘socialism’ than today’s China.

  12. avatar K42inSEA says:

    The dial goes to 11!

    1. avatar James69 says:

      Why didn’t they just make 10 brighter?

  13. avatar leo says:

    what is new in this red dot and why it is better than $50 Bushnell Trs25?

  14. avatar tsbhoa.p.jr says:

    if trs25 fails on the non- reciprocating deagle mount i’ll consider a lifetime warranty. i would understand if this constituted abuse.
